Natural materials can provide cost-effective way in the development of various products for specific applications. On the hand, physicochemical properties of composite materials can be enhanced to perform a specific process of interest such as wastewater treatment. Clay materials have been used for many applications including brick making and wastewater treatment. To enhance the properties of natural materials such as clay, multiwalled carbon nanotubes (MWCNTs) were used to enhance the properties of natural clays. Natural clays and MWCNTs composites were characterized to provide insights as a starting point for various applications. There are two sets of data presented in this study: i) raw material, unheated and heated (at 900 °C); ii) natural clay, MWCNTs and natural clay/MWCNTs composites. The chemical composition and phase identification analyzes were carried out using X-ray Fluorescence (XRF) and X-Ray Diffraction (XRD), respectively. A Fourier-transform infrared (FTIR) spectrometer was used to determine the functional groups of the samples. The UV-vis analyzes were carried out to investigate the reflectance percentage of the natural clays and the composites samples. The Thermogravimetric analysis (TGA) analyzes were performed to investigate the weight loss and dehydration process of the samples. The presented data showed that natural clays and natural clays/MWCNTs composites can be used for various applications such as construction industry, for cosmetic usages and for the removal of pollutants in aqueous solutions.
